- 摘要:
- 基于城市建设用地的生态适宜性对建设用地资源进行合理有效开发利用是缓解城市化进程与土地资源有限性矛盾的根本途径。因此，在前人研究的基础上，提出了结合网络分析法（Analytic Network Process，ANP）与GIS的城市建设用地生态适宜性耦合评价模型，并结合长春市的自然、社会和经济特点对长春市城市建设用地生态适宜性进行案例研究，最终获得了可视化的长春市城市建设用地生态适宜性空间分布图（5个适宜度）。结果表明：对于长春市建设用地的选取最适宜的土地面积约为1 289.3 km2，适宜区域6 662.7 km2，较适宜区域9 461.4 km2，一般适宜区域2 848.2 km2，不适宜区域303.4 km2，而且长春市建设用地生态适宜性较高的地区（最适宜区域和适宜区域）分布在长春区域的腹地，处于长春市市区以及九台区、德惠市、农安县的交汇的区域，该地区自然、社会和经济各项指标的生态适宜性度均相对较高，表明长春市未来的城市发展以及城市建设的重点可以向生态适宜度较高的中部地区偏移。研究结果说明了ANP-GIS耦合模型的可靠性，同时也为长春市的建筑用地的选取和长春市的城市规划提供决策依据。
- Abstract:
- Ecological suitability of the urban construction land is the fundamental way to alleviate the contradiction between the urbanization process and the land resources. According to the previous research, Analytic Network Process (ANP)-GIS integrated model was adopted to build up the ecological suitability evaluation of urban construction land in Changchun, combined with Changchun City’s natural, social, and economic characteristics. Finally,a visualized spatial distribution map(five suitability degrees) of ecological suitability of Changchun urban construction land was obtained. From the ecological suitability map, it can be seen that the most suitable land area for the construction land selection in Changchun is approximately 1 289.3 km2, the suitable area is 6 662.7 km2, the more suitable area is 9 461.4 km2, and the general suitable area is 2 848.2 km2, an unsuitable area 303.4 km2. The areas with high ecological suitability (the most suitable area and suitable area) for construction land in Changchun City are located in the hinterland of the Changchun region,where the degree of ecological suitability of natural, social, and economic indicators is relatively high. It indicates that the city’s future urban development and urban construction priorities can shift to the central region where ecological fitness is relatively high. The results showed that the reliability of ANP-GIS coupling model and provides the decision-making basis for Changchun’s construction land selection and Changchun city planning.
